MUFFLER.

Specification of Letters Patent.

Application led April 8, 1910. Serial No. 554,105. f y v lie it known that l, JoiiN J. RADELL, citizen ot the United States, residing at Utica, in the county ot' Uneida and State rot" New York, have invented certain new and useful lmproveniente. in Mulllcrs, of which the 'tolinutller adapted more particularly for use on explosive engines of automobiles, although it -inay be used on any explosive engine. i

The invention 'further contemplates certain improvements over an application for improvement in mutilers lil-ed by me on the 7 th day ot January, 1910.

The improvement consists in providing one or more of a plurality of' cups, which make up the mufller, with a pivotally mounted auxiliary shield or disk provided with apertures. By rotating this disk or shield it can be made to close the apertures in the partition of the cup to which it is pivotally mounted or it` can by rotation inv the opposite direction leave the apertures in the partition ofthe cup partially or entirely open according to the desired position vwith reference to back pressure ot the mutller. Said auxiliary shield or disk is rotated vor rather vibrated by a rock lever which may be actuated for short movements by a screw or in case of vlonger movements by a treadle to which it is intermediately connected. A inulller provided with this auxiliary shield or disk can be easily adjusted with reference to back pressure to any explosive engine and furthermore perm-its of an open or cut 'ouft exhaust when 'the engine is vunder great strain, as when the. automobile is ascending a hill or under any like circumstance.

Further objects will appear in View of the drawings in whichl i 1 i Figure l is a side elevation of the muiler complete; Fig. 2 is a longitudinal transverse A section ofthe mutller; Fig. 3 is a plan View,

looking in the direction of the arrows in Atheir respective cups.

Fig. '2, of the partit-ion of a cup provided with the improved shield or disk; Fig. 4f is a fragmentary detail view of certain parts and Figs. 5 and (3 are details somewhat enlarged ot' certain parts employiul in the device; Fig. 7 is la transverse seetion'of a rock shaft showing a lever connected thereto.

Fig. S is a detail of a t-readle of an automobile to which the muliier may be connected.

Referring to the drawings more particulai-ly, the in uflier comprises a series of independent, detachable cups denoted by 1, 2, 3, 3 and 4, held together by a plurality of hollow tubes 5, two only being here shown. The cups are provided with partitions having suitable apertures a for the insertion oi tubes 5, in order to assemble the cups. Hollow tubes 5 have their ends open, in order to connect their interiors `with the atmosphere to form air passages adapted to lower the temperature' of the medium within the mutlier. Cups 2, 3, 3a and 4- each have one edge formed with a shoulder as at 6 adapted to seat the beveled edge 7 of the preceding cup. Cup l has bot-h edges beveled as at 7 and 9. The beveled edge 9 rests against the corresponding beveled edge ll of end piece Patent-ed Apr. t8, 1913i.

12. Remote end pieces '13 has a beveled edge i 14 adapted to correspond with beveled edge 7" of cup 3, .As shown in Fig. 2 the edges of each succeeding cup reinforce those of the preceding ones and the end pieces have edges adapted to reinforce the adjacent edges ot' Cups 2, 3. 3a and 4 are also each provided with a partition having openings partly closed by-angularly disposed lianges l5 and are arranged in series of 2,13, 4. preferably. Cup 2 having'a partition with the greatest numbero openings disposed nearest the inletport 16 of the eX- haust and the remaining` cups 3 and l having partitions arranged willi reference to openings in a diminishing progression or order. Tubes 5 have their ends externally screw threaded as at 22 upon .which is screw mounted nuts 23 in order to' hold the 4cups in assembled position. The' above mentioned parts are more fully described iii an application filed by me January 'i'. 1910, and 'l therefore refer to thatapplication for a vmore complete understanding of the. above described part-s. l

partition ot' cup 3a. The disk Q4 has a wing 25 provided with a slot 26 in which loosely .iced

sembled position.

rests'the end 27 of rock lever 28. Rock lever 28 is rigidly mounted upon. rock shaft 2t) preferably in the manner shown most clearly in Fig. 7. Lever 28 has its end enlarged somewhat. The enlargcl portion is provided with a square aperture B adapted to tit'over acorresponding square portion C on shaft 2t) and held rigidly to shaft .25) b v set sc1ew l). Rock shaft 29 is journaled at one end in bracket bearing 3() pendent from transverse partition 3l' of cup 3a. The other end of rock shaft 29 has a bearing in the side 3'. of cup 3a. The bearing in side 32 of cup 3 is reinforced by bearing bushing rigidly secured to s1de 32.' Rock shaft 29 is provided with a right angularly disposed portion or arm 34 ada ted to beheld normally against the end of adjustment screw 35 screw mounted in horizontal portion 3G of bracket 3T. Lock nut 3S is screw mounted upon screw 35 and is adapted to be Iscrewed down tight to horizontal portion S6 of bracket 37 in'order to hold screw 35 in any desired adjusted vertical position. Pendent from bracket 3T is arm Bt) having horizontal portion 40 adapted to hold spring tl in as- A\rm llt) does not hang vertically down from bracket 3T but is disposed; at an angle in order that spring 41 may be held to one side of screw 35. Such arrangement makes it possible to more cons veniently manipulate screw' 35 without interfering with spring 11.

Bracket bearing 30 is held to transverse partition 3l of cup 3" preferably by rivets. Bearing bushin r 33, bracket 3T, horizontal portion 36, arm t) and its horizontal portion 40 are preferably cast in one piece and the whole is riveted to side 32 of cup 3.

The o eration of the muttler with reference to t 1e improvement may be described as follows: The exhaust enters the chamber provided by cup l by way of port lo which is suitably connected to the exhaust pipe of the engine by being screw mounted thereto. When the exhaust has entered the chamber of cup 1 it seeks or rather lis urged to go far`- ther subsequent explosions which drive the exhaust through the apertures in the par tition of cup 2, said apertures being partly closed by flanges 15 tending to conduct the exhaust toward the sides ot' the niutlier or toward the hollow tubes kept cool bv the passage of air. The exhaust enters each cup 1n succession and in each instance is directed by the flanges l5 toward the sides of the entering cup. \V hen the exhaust enters the next to last cup or cup il its further passage forward is impeded or irogressed b v the position of auxiliary shield or disk 24 with reference to openings 40 in the partition 3l of cup 3a. In order to regulate the size of openings from cup 4 or the preceding cup to cup 3 or in other words in order to turn ishield or disk 24 upon its pivot, so that its openings will register to any degree with openings 40 .in partition 31 of cup 3, I roA tate rock lever 28 whose end 2 projects through slotted opening D in transverse partition 3l of cup 3 and into opening 2b ot' auxiliary shield or disk 24; 'By turning screw upward it will raise arm 3-t ofrock shaft 9A andthus cause the leve" :28 to rock and rotate disk 2t whereby the openings of disk 2t may be brought to register with the openings of transverse partition 251 of cup :if with a view of relieving the back )ressure of themntiler.A If at any time it is desirable lto have a complete exhaust or cut out, l provide a wire sto connected to arm 3l of rock. shaft 29. A'ire Lb may be connected to a treadle at? within convenient reach of the chautl'eur`s foot, so that by bearing down on the treadle, wire 4G will be pulled 111 a direction that will raise arm 34 of rock shaft Q21 from off its normal seated position on the end of screw 35 and thus rotate lever b' and disk 'l-lsufliciently to have the openings ot' the disk A exactly register with openings l0 in partition El of cup 3, The exhaust may then escape through outlet port 13. When the end :2T of rock lever 2b is at one 'extreme of slot 45 in transverse partition 31 of cup 3, the auxiliary disk 4 will completely close openings t0 of cup 3 and when the end of the lever is at the other extreme of slot 45, the disk Qt will be rotated so that its openings 40 will exactly register with openings 40 of'cups r. The arrangement will then give a maximum opening.

Many moditications may be made in the invention without departing from the principle thereof.
